As far as I understand, in order to track our quota usage, we need to provide our API key to the Google App Service on the service we are planning to use.
In my case
As of 7/13/2017, I was able to get the API to function by enabling the Sheets API in both the "Advanced Google Services" menu (images 1 and 2), and in the Google Developer Console. If you're logged into Google Sheets with the same email address, no fetch function should be necessary.
[In the Resources menu, select Advanced Google Services.][1]
[In Advanced Google Services, make sure the Google Sheets API is turned on.][2]
